Acceptance criteria • All tests run with a single command on Mac, Linux, or CI. • Reports show pass/fail for each scenario and step. • Code is clean, typed, and pushed to our private Git repository. If you can also wire this into our existing CI pipeline, let me know&mda...

I’m putting the finishing touches on a peer-to-peer infrastructure built for fast, secure file sharing and now need a polished desktop interface to match. The entire product lives on the desktop, so every screen you design must feel at home on Windows, macOS and Linux alike. The aesthetic I’m after is minimalist and clean—no visual noise, just the essentials presented with clarity. The core user journey is simple: pick files, choose peers, watch the transfer, then review history. Your job is to turn that flow into an intuitive, good-looking experience. You’ll receive low-fidelity wireframes and a concise feature list; from there I need high-fidelity visuals in Figma or Sketch, complete with a small component library, colour and type tokens, and light/dark...

I want a fully customised Debian-based distribution that carries my visual identity from the very first boot screen through to the desktop environment. This means replacing the splash/boot animation, GRUB theme, wallpapers, icon set, GTK/Qt theme and default fonts with artwork I will supply (or that you can create to match my style guide). Beyond appearance, the distro should still behave like standard Debian so that users can access the usual repositories and updates without breaking anything. No extra software needs to be bundled unless it is required for the theming itself. Deliverables • Bootable ISO (UEFI & Legacy) with all branding elements applied • Source files or scripts used for the build so I can reproduce future versions • Short read-me outlining how to...

I need help giving my current Linux-based messaging stack a refresh. The plan is to deploy the latest EMQX broker, migrate my existing MQTT topics to it, and stand up an IEC server that can exchange data seamlessly with the new broker. Here is what I’m looking for: • Clean installation and hardening of EMQX on my Linux host, including TLS, user authentication, and optimised config files. • Migration or recreation of all current MQTT topics and retained messages so nothing is lost in the switch. • Configuration of a companion IEC server and a reliable bridge to EMQX so data can flow both ways in near-real time. • Basic test scripts or commands that prove publishing, subscribing, and IEC interoperability work end-to-end. • Short hand-off document...

... The player's name and number will be provided as a text file. You can use FastAPI (Python) or an ASP.NET Core API (C#). The API or dashboard will (re)initiate the worker (there are multiple workers) and keep sending frames via the API. We can set the number of workers to 3 as a start, but it can be scaled to an unlimited number. Your engine will work in both GPU- and non-GPU Windows/Linux environments and return lists of sports data to the front end during continuous frame delivery. You will need to create a simple front end to show that your system works. • Bidding Your bid is my budget.

Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PH...

...CI/CD workflow and tighten the security of a handful of Linux servers. On the CI/CD side, everything lives in GitLab. I need practical guidance on structuring ., optimising runner usage, and setting up automated staging-to-production deployments with roll-backs and clear version tagging. If you have shortcuts for caching, parallel jobs, or environment-specific variables, even better. The servers behind those pipelines also need attention. Your job is to harden them—from SSH policies and firewall rules to OS-level patching and intrusion detection—so they’re production-ready once the pipeline pushes new code. Deliverables • A working, documented GitLab CI pipeline that builds, tests, and deploys automatically • Hardened Linux server configura...

to build. Your job is to make whatever minimal source tweaks or build-script additions are needed, and demonstrate a clean compile and working with GCC. I don’t mind whether you work on Linux, macOS, or Windows—just make sure the final instructions let me reproduce the build on a fresh machine running a recent GCC release. What I expect back from you: • Updated source files or patches only where strictly necessary. • A or Makefile (whichever you prefer) that invokes GCC and completes without warnings or errors. • A short README that lists the exact GCC version you used and the commands I should run, plus any system packages I must install first. I’ll consider the job done when I can clone the repo, follow your README,

...without changing how it behaves. My goal is simple: open the same interface and get the same results, only now over the internet instead of from a pen drive. Preferred environment is a Linux server. I’m open to whichever method makes most sense there—Wine, a lightweight Windows VM, containerisation, or even a web-friendly wrapper—as long as the end-user experience stays identical. Database handling is the one grey area: the app might be using flat files or an old Access database. I’ll need advice on whether we keep that structure, migrate to MySQL/MariaDB, or adopt another engine that plays nicely under Linux. What I’d like from you: • A proposed approach that preserves all current functionality. • Milestones with realistic time...

I regularly roll out visual assets for social-media campaigns and host every file on my own server. What I now need is a lightweight, reusable solution that turns each of those images into a hyperlink so that, on click, the viewer is instantly redirected to the correct website. You’ll be working inside a standard Linux/cPanel environment, so simple HTML with a touch of CSS or vanilla JavaScript should do the trick—no heavy frameworks required. Please keep the code clean, well-commented, and easy for me to update when a destination URL changes. Deliverables • A plug-and-play code snippet (HTML + optional CSS/JS) that makes any uploaded .jpg or .png redirect on click. • A brief read-me or quick Loom walkthrough showing exactly where to drop the code and how...
